Portland Cement Association is a non-profit organization that promotes the use of concrete. The organization conducts and sponsors concrete research, participates in setting cement manufacturing standards, and disseminates free designs of concrete-based architectural structures, among other functions.WikipediaCarbonation is generally a slow process. In high-quality con-crete, it has been estimated that carbonation will proceed at a rate up to 1.0 mm (0.04 in.) per year. The amount of carbonation is significantly increased in concrete with a high water-to-cement ratio, low cement content, short curing period, low strength, and highly permeable or ...

Apr 03, 2020 Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.
